If you're experiencing poor thread tightening with your SunStar Sewing Machine, it might be due to weak tension in either the upper or lower thread; try adjusting the tension of the upper and under thread. Also, the timing between the needle and shuttle might be improper; in this case readjust the timing of needle and shuttle.
What causes ineffective sense of upper thread on SunStar SPS/B-1306 Sewing Machine?
If your SunStar Sewing Machine isn't sensing the upper thread effectively, it might be due to a bad connection between the take-up lever spring and detecting plate. Clean these parts and adjust the tension of the take-up lever spring and connecting condition of detecting plate. Another cause may be a bad connection of the wire with the thread sensor plate, so reconnect the wire with thread sensor plate.
Why is the thread cutting on my SunStar SPS/B-1306?
If the thread is cutting while using your SunStar Sewing Machine, several factors could be at play. Ensure the thread is inserted correctly and the needle is properly installed, paying attention to its height and direction. A damaged needle, indicated by bending, cracks, or abrasion, should be replaced. Adjust excessive tension in both the upper and lower threads, as well as the take-up lever spring. Finally, inspect the shuttle surface spring for cracks, and replace it if necessary.
Why is my SunStar SPS/B-1306 skipping stitches?
If your SunStar Sewing Machine is skipping stitches, it could be due to several reasons. A bent or improperly sized needle should be replaced. Ensure the needle is correctly installed. The timing between the needle and shuttle may be off, requiring readjustment. Also, a large interval between the needle groove and shuttle point can cause this issue, so readjust the timing. Finally, excessive tension and stroke of the take-up lever spring might be the cause, requiring adjustment.
